wean

wean: [OE] The etymological notion underlying wean is of ‘becoming accustomed’. The specialization to ‘making accustomed to food other than mother’s milk’ is a secondary development. The word comes from a prehistoric Germanic *wanjan (source also of German gewöhnen ‘accustom’). This was derived from the adjective *wanaz ‘accustomed’, which in turn was formed from the base *wan-, *wen-, *wun-(source also of English winsome, wish, and wont ‘accustomed’ [OE]).
=> winsome, wish, wont

wean (v.)

"train (an infant or animal) to forego suckling," c. 1200, from Old English wenian "to accustom, habituate," from Proto-Germanic *wanjan (cognates: Old Norse venja, Dutch wennen, Old High German giwennan, German gewöhnen "to accustom"), from PIE *won-eyo-, from root *wen- (1) "to desire, strive for." The sense of "accustom a child to not suckling from the breast" in Old English generally was expressed by gewenian or awenian, which has a sense of "unaccustom" (compare German abgewöhnen, entwöhnen "to wean," literally "to unaccustom"). The modern word might be one of these with the prefix worn off, or it might be wenian in a specialized sense of "accustom to a new diet." Figurative extension to any pursuit or habit is from 1520s.
